I found some interesting news. Ford is going to offer All-Wheel-Drive on the 2020 Transits. I was a week away from ordering a 2019 Promaster when I read about this at Pick-up truck . com. I then went to the Ford web site and they have the new 2020 Transits in the future vehicle page of their web site.
It looks like I'll be waiting until the 2020s come out and I'll be buying a Ford for my next adventure camper. On a related note I went to talk to my local Sprinter dealer and was told that I could not order a van the way I wanted and I would just have buy what was sent by the factory. This seems odd to me and I will look into this further. I'll keep you all posted on what I find.
